Green Mode Fairchild Power Switch (FPS™)  
Features  
Description  
The highly integrated FSBH-series consists of an  
integrated current-mode Pulse Width Modulator (PWM)  
and an avalanche-rugged 700V SenseFET. It is  
specifically designed for high-performance offline  
Switch Mode Power Supplies (SMPS) with minimal  
external components.

Brownout Protection with Hysteresis  
Built-In 5ms Soft-Start Function  
Internal Avalanche-Rugged 700V SenseFET  
No Acoustic Noise During Light-Load Operation  
High-Voltage Startup  
The integrated PWM controller features include a  
proprietary green-mode function that provides off-time  
modulation to linearly decrease the switching frequency  
at light-load conditions to minimize standby power  
consumption. To avoid acoustic-noise problems, the  
minimum PWM frequency is set above 18kHz. This  
green-mode function enables the power supply to meet  
international power conservation requirements. The  
PWM controller is manufactured using the BiCMOS  
process to further reduce power consumption. The  
FSBH-series turns off some internal circuits to improve  
power saving when VFB is lower than 1.6V, which allows  
an operating current of only 2.5mA.  
Linearly Decreasing PWM Frequency to 18KHz  
Peak-Current-Mode Control  
Cycle-by-Cycle Current Limiting  
Leading-Edge Blanking (LEB)  
Synchronized Slope Compensation  
Internal Open-Loop Protection  
VDD Under-Voltage Lockout (UVLO)  
VDD Over-Voltage Protection (OVP)  
Internal Auto-Restart Circuit (OVP, OTP)  
Constant Power Limit (Full AC Input Range)  
Internal OTP Sensor with Hysteresis  
The FSBH-series has built-in synchronized slope  
compensation to achieve stable peak-current-mode  
control. The proprietary external line compensation  
ensures constant output power limit over a wide AC  
input voltage range, from 90VAC to 264VAC  
.
VIN Pin for Pull-HIGH Latch Function and Pull-  
LOW Auto-Recovery Protection  
The FSBH-series provides many protection functions. In  
addition to cycle-by-cycle current limiting, the internal  
open-loop protection circuit ensures safety when an  
open-loop or output short occurs. PWM output is  
disabled until VDD drops below the VTH-OLP, then the  
controller starts up again. As long as VDD exceeds 28V,  
the internal OVP circuit is triggered.  
Applications  
General-purpose switch-mode power supplies and  
flyback power converters, including:

Auxiliary Power Supply for PC and Server  
Compared with a discrete MOSFET and controller or  
RCC switching converter solution, the FSBH-series  
reduces total component count, design size, and  
weight; while increasing efficiency, productivity, and  
system reliability. These devices provide a basic  
platform that is well suited for the design of cost-  
effective flyback converters, such as in PC auxiliary  
power supplies.
